Top Creatives: How to Select a Color for Call-to-Action Buttons

In a mobile game ad creative, you want to grab a gamer’s attention, attempting to persuade him or her to click-through to a desired app store and download a game. A call-to-action (CTA) button is a visual element within many ad creatives that’s meant to entice a gamer to click it and go to a game’s app store page.


Color is one of the most powerful visual cues to consider in a CTA button. Your choice of color can be the difference between getting a gamer to click-through or not. For the uninitiated, color is more than just a visual property. Colors can evoke different emotions in people, resulting in different reactions. For example, red elicits good luck in China, while the same emotion is associated with green in North America.

Global CPIs Stand Pat in October

We saved you the best treat for last. Although the coffin is sealed shut on Halloween, that didn’t stop us from digging up October CPI data in the Chartboost Network. In October, global CPI rates on iOS and Google Play were stable. Minor fluctuations month-over-month among iOS and Google Play wasn’t too surprising. The trend most likely points toward advertisers preparing for a hectic holiday season.

We share this kind of data on the Chartboost Blog because “transparency” is our middle name. Insight into CPI trends by country and platform grants game developers access to data that will help them drive user acquisition cost down and profitability up.


We’d like to give a thank you to Phil for his flattering words about Chartboost and for sharing our CPI data.

Focus on Localization to Find Worldwide Niches Everyone is Ignoring

Today’s guest post comes from Evaldo Rossi, Founder of WordData – App Store Optimization (ASO).


Although the trend points to an ever-increasingly connected world, you can’t expect that it’s possible to run the same marketing campaign worldwide and get the same results. Even with globalization, the one-size-fits-all approach probably won’t work. Cultural, lingual and economic barriers keep that from being a feasible plan. And this translates (no pun intended) to the iOS App Store.



In order to optimize your app’s performance worldwide, you have to—at the very least—localize your marketing assets. You must make a serious effort. You have to hire freelancers to translate all marketing copy (app name, description, screenshots), upload copy for each language to an app store (five sets with five screenshots each), and perform keyword research and optimization for each market.


Basically, if you want to market your app in other countries, you must apply App Store Optimization (ASO) for each language.


And therein lies opportunity. Hidden gems and unexplored niches await you in your localized ASO. It’s hard to find these gems, but that’s why they are there. By optimizing for a specific language, you will increase the number of downloads from your campaign, resulting in a cheaper eCPI and better worldwide performance.

New Languages! 新しい言語! 新的语言! Новые Языки!

We made some international noise in July with the announcement of our partnership with Beijing-based Chukong which was only part of a bigger global push for us. Today, we’re also happy to report that Chartboost supports multiple languages: English, Japanese, Simplified Chinese and Russian so you can create campaigns in your native tongue.


We’re always focused on helping you succeed in every way possible, and removing language as a barrier to optimize your business strategies can be a game changer. By localizing our website, Dashboard, and Help Site, we’re making it easier for you, our global mobile game devs, to leverage our platform to get the tools you need to monetize or acquire new players.


Japan, China and Russia are our largest non-English-speaking markets so we decided to kick off our international expansion in those countries. You can update your language preferences at the bottom right of the Dashboard, which will automatically save as your default language in your profile account settings.


We’re just trying to empower you to be you—we want to speak your language. Stay tuned for further localization updates, but in the meantime, try your preferred language across our platform today.

Top Creatives: Puzzle

Some things just go together–peanut butter and jelly, burger and fries, Bert and Ernie, and puzzle games and mobile devices. Puzzle is one of the most prominent game categories that translates perfectly to touchscreen devices. For instance, the touchscreen interface mimics the tactility of a jigsaw puzzle and the physics of a block puzzle.


If the Puzzle category in the Chartboost Network was a jigsaw puzzle, it would be marked at expert level. The Puzzle category is highly competitive and takes an outstanding creative to stand out from the pack, but that’s what we’re here for. In this month’s Top Creatives series, we connected all the pieces, stacked all the blocks and popped all the bubbles, to find the common best practices among the top performing creatives in the Puzzle category with superb impression-to-install conversion.

How ClutchPlay Cracked ‘Skullduggery!’ With Playtesting and Marketing

We recently sat down with Amy Dallas, a Chartboost University (CBU) spring 2014 alum and the co-founder and producer of ClutchPlay Games. Amy and her studio just released their second game Skullduggery! on iOS yesterday, which was also selected as this week’s Editors’ Choice on the Apple App Store.



Howdy, Amy! Thanks for taking the time to sit down with us. Could you give the Chartboost community a little refresher about ClutchPlay Games?


Amy Dallas: ClutchPlay Games is a small, scrappy indie studio in Portland, Oregon. The four of us initially worked together for several years at the Portland, Oregon satellite office of a large mobile game company based in San Francisco. In early 2012, we walked into our office one day to learn that we had been downsized out of existence.


While it wasn’t a great time for any of us, we all realized that this was one of those “now or never moments.” We had the right team at the right time and each of us had saved enough money to live without a paycheck for almost a year. So that’s what we did.


We launched our first game, Little Chomp, in October 2012. Now we just launched our second game Skullduggery! on iOS yesterday.
